US Citizenship Test Prep

US Citizenship Test Prep gives you 20 mock exams of 20 questions for the 2025 U.S. civics test, covering the principles of American democracy, the system of government, rights and responsibilities, American history, geography, and symbols and holidays. Every answer in Mock Exams 1–7 is explained for free: on our public study pages without signing in, and in your exam review with a free account. Interview practice reads questions aloud so you can answer out loud, like the real oral test. Premium unlocks Mock Exams 8–20 and adds interview practice with every question, full statistics and missed- and flagged-question practice.

It’s the web version of our iPhone app, with the same 400-question bank. The questions are our own wording, based on facts in the official USCIS study materials (opens in a new tab) for the 2025 civics test. Questions whose answers change (such as the current President or your senators) aren’t included; check uscis.gov/citizenship/testupdates (opens in a new tab) for those.

US Citizenship Test Prep is developed by ChowChow Labs, an independent app studio based in Toronto, Canada.

Every explanation on our free practice pages links to the official USCIS study page for its section. If you spot a mistake, use the “Report a problem” link under any question or email us, and we’ll check it against the official materials and fix it.

US Citizenship Test Prep is an independent study aid made by ChowChow Labs. It is not affiliated with, endorsed by, sponsored by, or approved by U.S. Citizenship and Immigration Services (USCIS) or any U.S. government agency. It is not the official civics test, and practice scores don't guarantee you'll pass. Always study the official USCIS materials.
